C_[ACTION]_shared

C_[ACTION]_shared#

The benchmark of a collective access from all processes to a common file, with a shared file pointer.

This benchmark is based on the following MPI routines:

  • MPI_File_read_ordered/MPI_File_write_ordered for the blocking mode

  • MPI_File_.._ordered_begin/MPI_File_.._ordered_end for the nonblocking mode

All other parameters and the measuring method are the same as for the P_[ACTION]_shared benchmark.
